[0001] This application relates to the field of powered aircraft technology, and more particularly to an aircraft and its tilting system. Background Technology

[0002] In existing compound wing aircraft designs, the motors are typically used only to provide lift or thrust, and in fixed-wing configurations, the rotor motors are essentially dead weight. Furthermore, in rotor configurations, the lack of effective vector control reduces the aircraft's maneuverability and operational flexibility. Utility Model Content

[0028] The following embodiments further illustrate the technical solutions of this application. It should be understood that the specific embodiments described herein are merely for explaining this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not all of them.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The term "aircraft" is defined as an air transport system of any size having at least one lift propeller as its propulsion source. The term "aircraft" can include both "manned" and "unmanned" air transport systems. A manned aircraft can mean an air transport system carrying one or more human passengers, none of whom have control over the aircraft. A manned aircraft can also mean an air transport system carrying one or more human passengers, some of whom, or one of whom, has partial or full control over the aircraft. An unmanned aircraft can mean an air transport system that does not carry any human passengers and flies autonomously or is remotely controlled by someone at a distance.

[0032] In this specification, "aircraft" includes manned aircraft and any unmanned vehicle, such as unmanned aerial vehicles (UAVs), unmanned aircraft, remote-controlled aircraft, unmanned aircraft systems, any aircraft classified by the International Civil Aviation Organization (ICAO) under cycle 328AN / 190, and so on. As an example, a drone can take the form of a single- or multi-rotor helicopter (such as a quadcopter) or a fixed-wing aircraft. Furthermore, certain portions of this disclosure can be used in conjunction with drones in the form of other types of unmanned vehicles (e.g., wheeled, tracked, and / or watercraft).

[0033] Embodiments of this application are described below with reference to the accompanying drawings, such as Figure 1 As shown, Figure 1 An aircraft tilting system according to an embodiment of this application is described in general, including: a motor 100 and a tilting mechanism 200 connected to the motor 100.

[0034] The tilting mechanism 200 is configured to reciprocate within a preset angle range, thereby driving the motor 100 to reciprocate within the preset angle range.

[0035] Specifically, in one embodiment, the preset angle is preset to a range of 0 to 90 degrees, which means that the tilting mechanism 200 can rotate within the range of 0 to 90 degrees, thereby driving the motor 100 to rotate within the range of 0 to 90 degrees, so that the motor 100 can switch between lift mode and thrust mode according to different angles when stationary.

[0036] In another embodiment, the preset angle range can be other values, such as 0 degrees to 100 degrees. In this embodiment, the maximum extreme angle of 110 degrees is greater than 90 degrees in the previous embodiment. In this way, when the tilting mechanism 200 swings to 90 degrees, there is still an elastic buffer zone for it to continue swinging upward. This application does not impose any restrictions on the specific angle.

[0037] Please refer to now. Figures 2 to 4 , Figures 2 to 4 The specific structure of the tilting mechanism 200 is shown in the figure. The tilting mechanism 200 specifically includes a motor base 110, which is used to accommodate the motor 100.

[0038] Specifically, the tilting mechanism 200 also includes a first connecting rod 210 and a second connecting rod 220 connected to each other. The first connecting rod 210 has two ends, namely a first end 2101 and a second end 2102. Similarly, the second connecting rod 220 also has two ends, namely a first end 2201 and a second end 2202. The first end 2101 of the first connecting rod is connected to the motor base 110, the second end 2102 of the first connecting rod is connected to the first end 2201, and the second end 2202 of the second connecting rod is connected to the mounting base 330. The connection between the first connecting rod 210 and the second connecting rod 220 can be a hinge or a bolt connection, and this application does not impose further limitations. In this embodiment, the first connecting rod 210 and the second connecting rod 220 are bolted together.

[0039] Please continue reading now. Figures 2 to 4 In addition, the tilting mechanism 200 also includes a first mounting member 230 and a second mounting member 240 that are connected to each other. The first mounting member 230 is fixed on the motor base 110, and the second mounting member 240 is fixed on the mounting base 330. The connection between the first mounting member 230 and the second mounting member 240 can be achieved by hinge or bolt connection, and this application does not impose any further restrictions.

[0040] Please continue reading now. Figures 2 to 4 In addition, the tilting mechanism 200 also includes a drive mechanism 250, which is used to drive the tilting mechanism 200 to rotate. The drive mechanism 250 can be a hydraulic push rod, a pneumatic push rod, or other drive structure with driving function. This application does not impose further restrictions.

[0041] Please refer to now. Figure 5 It should be noted that in this embodiment, the tilting mechanism 200 has two first through holes at the end of the first mounting member 230 away from the motor base 110, and two second through holes at the end of the second mounting member 240 away from the mounting base 330. The radial directions of the first through holes and the radial directions of the second through holes together form the rotation axis X.

[0042] Specifically, the radial direction of the first through hole refers to the axial direction of the first through hole, and the radial direction of the second through hole refers to the axial direction of the second through hole. The first through hole and the second through hole are arranged parallel to each other along the axial direction and overlap in the transverse direction perpendicular to the axial direction. In this way, the first through hole and the second through hole together form a rotating axis X along the radial direction, and under the drive of the drive mechanism 250, the first mounting member 230 and the second mounting member 240 swing back and forth around the rotating axis X.

[0043] Please continue reading now. Figure 5Driven by the drive mechanism 250, the first mounting component 230 and the second mounting component 240 reciprocate around the rotation axis X within a preset angle range, thereby driving the first connecting rod 210, the second connecting rod 220 and the motor 100 to reciprocate together within the preset angle range.

[0044] Please refer to now. Figure 6 , Figure 6 The specific structure of the first link 210 is shown. In one embodiment, the first link 210 has an I-shaped cross-section and two first connecting portions 2101. Two first connecting portion through holes 2103 are opened at the ends of the first connecting portions 2101. In other embodiments, the first link 210 has a circular cross-section or any other shape. This application does not impose any restrictions on this.

[0045] Specifically, in one embodiment, the first link 210 is flat in the thickness direction, and the flat thickness is beneficial to the flexibility of the first link 210 during rotation.

[0046] In another embodiment, the first link 210 has a certain thickness in the thickness direction. As long as the thickness does not affect the flexibility required for the first link 210 to rotate, this application does not impose any further restrictions on this.

[0047] Please continue reading now. Figure 6 In this embodiment, the first connecting rod 210 has two ends, namely a first connecting portion 2101 and a first fixing portion 2102, wherein the first connecting portion 2101 and the first fixing portion 2102 are respectively distributed at both ends of the first connecting rod 210. In this embodiment, the length of the first connecting portion 2101 is greater than the length of the first fixing portion 2102. Of course, in other embodiments, the length of the first connecting portion 2101 may be equal to or shorter than the length of the first fixing portion 2102.

[0048] In one embodiment, the number of first connecting parts 2101 is two, and in another embodiment, the number of first connecting parts 2101 can be three. This application does not impose further limitations on this.

[0049] Please continue reading now. Figure 6 In this embodiment, each first connecting part 2101 is provided with a first connecting part through hole 2103 for connecting the first connecting rod 210 to other components. Similarly, each first fixing part 2102 is provided with a first fixing part through hole for fixing the first connecting rod 210 to the motor base 110.

[0050] Please refer to the following: Figure 7 ,like Figure 7As shown, similar to the first link 210, the second link 220 has an I-shaped cross-section and two second connecting portions 2201, with two second connecting portion through holes 2203 in each portion. Of course, the cross-section of the second link 220 can also have other shapes, and this application does not impose any restrictions on this.

[0051] Please continue reading now. Figure 7 In this embodiment, the second connecting rod 220 also has two ends, namely a second connecting part 2201 and a second fixing part 2202. Each second connecting part 2201 is provided with a second connecting part through hole 2203 for connecting the second connecting rod 220 to other components. Similarly, each second fixing part 2202 is provided with a second fixing part through hole for fixing the second connecting rod 220 to the mounting base 330.

[0052] It should be noted that, in one embodiment, the connection between the first connecting part 2101 and the second connecting part 2201 is a screw connection.

[0053] In another embodiment, the connection between the first connecting part 2101 and the second connecting part 2201 is a hinge connection or other connection methods, and this application does not impose further restrictions on this.

[0054] Specifically, in order to ensure that the first connecting through hole 2103 and the second connecting through hole 2203 can be safely and reliably connected, the first connecting through hole 2103 and the second connecting through hole 2203 are arranged in parallel in the radial direction and overlapped in the transverse direction perpendicular to the radial direction.

[0055] It should be noted that the radial direction of the first connecting through hole 2103 and the second connecting through hole 2203 refers to the axial direction of the first connecting through hole 2103 and the second connecting through hole 2203. This allows bolts to be inserted into the first connecting through hole 2103 and the second connecting through hole 2203, connecting the first connecting through hole 2103 and the second connecting through hole 2203 together. Driven by the drive mechanism 250, the first mounting member 230 and the second mounting member 240 swing back and forth around the rotation axis X, thereby driving the first connecting rod 210 and the second connecting rod 220 to swing back and forth together, and ultimately driving the motor 110 to swing back and forth, thus switching to different modes according to the different positions of the motor 110.

[0056] Please refer to the following for details. Figure 8 , Figure 8 A schematic diagram showing the first connecting part 2101 and the second connecting part 2201 swinging back and forth within a certain angle range is shown.

[0057] Please refer to now. Figure 9 ,like Figure 9 As shown, the first connecting part 2101 and the second connecting part 2201 swing back and forth together within a certain angle range. When the first connecting part 2101 and the second connecting part 2201 are collinear on the same side, the motor 100 is in a horizontal position. At this time, the central axis of the motor 100 is parallel to the horizontal reference line of the ground. At this time, the mode of the motor 100 is the thrust mode.

[0058] Specifically, the first connecting part 2101 and the second connecting part 2201 are collinear on the same side. Specifically, with the axial direction of the first connecting part through hole 2103 and the second connecting part through hole 2203 as the reference line, the first fixing part 2102 and the second fixing part 2202 are located on the same side of the reference line, and the first fixing part 2102 and the second fixing part 2202 can be connected into a straight line.

[0059] Please refer to the following for details. Figure 10 ,like Figure 10 As shown, the first connecting part 2101 and the second connecting part 2201 swing back and forth together within a certain angle range. When the first connecting part 2101 and the second connecting part 2201 are collinear on opposite sides, the motor 100 is in a vertical position. At this time, the central axis of the motor 100 is perpendicular to the horizontal reference line of the ground. At this time, the mode of the motor 100 is the lift mode.

[0060] Specifically, the first connecting part 2101 and the second connecting part 2201 are collinear on opposite sides. Specifically, with the axial direction of the first connecting part through hole 2103 and the second connecting part through hole 2203 as the reference line, the first fixing part 2102 and the second fixing part 2202 are located on both sides of the reference line, and the first fixing part 2102 and the second fixing part 2202 can be connected into a straight line.

[0061] A second embodiment of this application also provides an aircraft including the aircraft tilting system 200 described above. The tilting system 200 allows the motor 100 to flexibly switch between lift and thrust, thereby maximizing the utilization rate of the motor 100.

[0062] The above embodiments are merely illustrative of the principles and effects of this application. Any person skilled in the art can modify or alter the above embodiments without departing from the purpose of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the purpose disclosed in this application should still be covered by the claims of this application.
